Is An Inverter Generator Better for RV

Inverter generators are small, light, and quiet in comparison to conventional generators. They are a better choice, but only if you want to run low-power devices.

Generators have quite a few types in various categories with different capacities. Some units run on different types of fuels. But another categorization can be done, and that is based on technology that they use to convert DC into AC power.

There are two types of such generators: conventional or standard generators and inverter generators. Inverters can convert DC into AC quite efficiently with a high frequency. Such a conversion process has no power fluctuations that are normal in conventional units.

Here you’ll find out whether these inverter generators are better than their standard counterparts or not.

What are Inverter Generators?

These units tend to draw power from a direct current source, a solar panel, or even a car battery. They convert the direct current power into alternate current power with the help of electronic circuitry.

This converted energy can be generated in various frequencies and voltages based on the equipment it will power. Most of the inverter units convert 12V direct current power from the DC source. It then transforms into 120V AC used by most of the appliances in your RV.

Inverters vs. Conventional Generators

Inverter generators are smaller and lighter. As a result, these units are quieter in operation in comparison to conventional generators. In addition, they can convert DC into AC at a high frequency and eliminate power fluctuations.

The same cannot be said for conventional generators, which have been around for a long time. These units have an energy source to power their motor. There is an alternator that produces electricity. In addition, they have an engine that requires a frequent 3000 RPM speed to run most households.

With the fluctuating engine, speed power output will fluctuate as well. There are different types of fuels used to power these units. You can also find gasoline, propane, and dual-fuel generators.

Besides, inverter units are better in most aspects than the standard units. But the decision to finalize your choice is not that easy. You will have to consider multiple factors before deciding to go for an inverter generator.

Factors to Consider Before Buying Inverter or Conventional Generator

Size and weight

One of the most significant advantages of using these inverter generators is their size and weight. This is because most inverter units can carry more power than their weight and size suggest.

Due to such size and portability, these units are best to transport and store. Looking for a unit that you can easily fit in your car for camping or RVing, an inverter unit is a suitable option.

Noise level

The noise level of these inverter generators is relatively low if you compare it with conventional units. This is because there is no engine running inside these units like the one there is standard. So, if you don’t like the noise of a running generator, this is the unit you need to go for.

Fuel efficiency and run time

Inverter units don’t have larger fuel tanks, just the ones that are there in conventional units. It means they will not run as much as the standard generators. These generators have a way of handling power to adjust power production according to the requirements.

This tendency to adjust power production according to the demand makes them highly energy-efficient. This way, these units can reduce any exhaust emissions and efficiently manage run times.

Quality of the power produced

Standard generators are just like engines running at their peak performance without regard for their load. The electricity produced here remains similar.

Inverters have to convert DC to AC. And this is where the DC capacitors level out the current before converting them into AC according to the required frequency and voltage.

Therefore, these units don’t have to rely on engine speed, and the power generated here is much cleaner. In addition, the quality is almost identical to what you get from your electricity supply company.

The quality of the power produced is important because most of our appliances today are highly sensitive to electricity. Without cleaner energy, they will end up malfunctioning or might get damaged. And this is precisely why solar generators are becoming trendy.


You will see an inverter generator is at a disadvantage against the standard units. Conventional generators will be useful if you need high power output. Otherwise, you will find an inverter unit more useful.

But these inverter units are quite expensive in repair and maintenance if you compare them with a standard unit. But this is the only disadvantage when it comes to an inverter generator.

Can I connect an inverter generator with a conventional unit?

If you already have a conventional unit and want to go for an inverter generator, it would be better to connect them in parallel. This way, you will double your power capacity.

With your parallel circuits, you can make your smaller inverters produce the same amount of energy as your more significant generator does. Then, when you connect your inverter with your generator, it will significantly improve the standard unit fuel efficiency.

Will connecting an inverter with a standard unit improve the quality of the current output?

When you connect your inverter with your standard unit, it will improve the quality of the current that is produced. You are equipping your generator with an inverter so that you will be getting the best of both worlds.

How efficient are inverters in terms of power generation?

Inverter generators are equipped to save up to almost 40 percent of fuel and have run time averaging around 10 hours. These numbers are more than enough for most users. These units can also help in reducing exhaust emissions.

Should I go for an inverter generator for my RV?

Yes, you can go for an inverter generator for your RV because most of the electricity demands will be fulfilled with such a unit. For a few personal electronics, along with a small RV AC, you will need an inverter that can range in capacity from 2000W to 3000W. You can go for a bigger inverter if you have a bigger AC or more to run.

What is the best inverter generator capacity for an RV?

The best inverter generator for your RV should range between 2000W to 4000W. Such a unit will work for most of the AC units in an RV, along with a variety of other appliances. Just make sure you go for an inverter unit bigger in capacity than your RV AC. For instance, if you have a 2000W AC, you should get a 3000W inverter generator. This will allow you to run some other appliances too.


Inverter generators are significantly better than their traditional counterparts. These units are silent and energy-efficient.

Due to their small size, these units are easy to carry and transport, and they won’t take up much space anywhere. In addition, these units are great for RVs because there are not many energy requirements in recreational vehicles.

You will need to go for an inverter with a bigger capacity than your AC. Or you will have to manage the supply on your own by turning some appliances off when you are running your AC. The point here is, inverter generators are quite useful, especially if you consider them for your RV.
